restore it on itunes
To erase an app on an ipod touch you put your finger on it and hold it down until they all start to move. Then you click on the x in the corner of the app you would like to erase. If you would like to erase a song you can not do that from the ipod. You need to go onto the computer you have it synced on and un-check it from your library.
